Executive summary and problems encountered 3
Executive Summery:

Problems Encountered:

1. Making X-axis dynamic via slicer by solving the DAX calculation to show the last 12 weeks from the end date.
2. Changed data source which is from the web site as my dashboard couldn't  be able to  refresh because one of the columns in          my source table was removed so I decided to change it.
3. Identifying the right KPI to tell the right story and make sense out of it.
